The adequate geological support and engineering of production processes requires mining companies to have structural geologists to be in charge for the acquisition, processing, analysis and preparation of geological and related data during development of a mineral deposit, starting from prospecting and exploration and up to reclaiming. In the prevailing practice, geologists of mining and servicing companies are mostly aimed at the appraisal and control of mineral resources while the study of geological structure of a deposit is assumed finished at the stage of prospecting and valuation as arule. At the later stages, geologists focus mainly on the quality and quantity of minerals, and geological bodies are often interpreted without regard to the actual geological structure of a deposit. The structural geology as a branch within a mining company should have a specific development strategy. This strategy is to account for the necessity of the other services for the input geological data, while the applied geological models should be used in mine design and be integrated in the production process. The intending specialists in the allied services should be informed on the available models, their value and completeness, as well as should possess free and intelligible access for operation. Efficient production management and risk control requires close communication between structural geologists, geomechanics, resource geologists, mining engineers, mineral dressing engineers and surveyors.

Geologic Data

Abstract Postdevelopment studies show that, once in operation, about 70% of mines perform below the prediction of their feasibility studies, with underperformance usually caused by deficiencies in the collection of primarily geology related data prior to designing the mine and planning its operation. A major reason for these deficiencies is probably a generally narrow understanding by many geologists of metallurgy as well as geotechnical and mining engineering. Additionally, geologists often do not appreciate the types and quantities of data required by metallurgists, geotechnical engineers, and mining engineers for mine design, planning, and operations. Critically, there is commonly inadequate communication between all four professional groups. For obvious and logical reasons, the principal focus of geologists has generally been considered the discovery of a mineral deposit and subsequent resource definition and estimation of its grade and tonnage, leading to the creation of detailed geologic and grade models of the deposit. While grade and tonnage are cornerstones to mine development, equally important to mine design is the geotechnical model, which is constructed progressively over three stages of mining study using information obtained from four separate geology-related models. Enhanced understanding of mining and metallurgy by geologists plus appreciation of the metallurgical and mining uncertainties inherent in geologic data by metallurgists and geotechnical and mining engineers can contribute to significantly improved mining outcomes.

Moderne Produktionstechnik liefert schon heute eine Vielzahl an Prozess- und Produktdaten. Diese werden häufig nur zur effizienten Steuerung von Maschinen verwendet. Weitergehende Ansätze des Advanced Analytics finden vor allem bei kleinen und mittleren Unternehmen (KMU) bisher kaum Anwendung. Der Beitrag zeigt und diskutiert generelle Einsatzmöglichkeiten und Potentiale von Advanced Analytics in Bezug auf ein effizientes Produktionsmanagement.   Modern production systems and technologies enable users to gather a wide variety of process and production data. These data are often only used for controlling machinery. Especially in small and medium sized enterprises the application of advanced analytics can be hardly found to seize the full potential of the gathered data. This paper discusses possible applications of advanced analytics and the potentials towards an efficient production management.

Abstract In this work, we present the problem of geo-environmental assessment of prospective areas of mineral deposits occurrence in Poland. T he issue is discussed mainly based on data from the database of Geo-environmental map of Poland, scale 1:50 000 (MGśP II). While for proven deposits a classification based on environmental conditions has been used for many years, for prospective areas of mineral occurrence such an assessment is not conducted. Taking into consideration not only protection of the natural environment, but also protection of mineral resources in Poland, it is necessary to review the approach to areas with prospective mineral resources from the point of view of their role in land use planning. Such prospective areas have - depending on the type of mineral in question, how large an area has been prospected, its geological structure - highly diverse surface area, from just a few to thousands of hectares. T his means the approach to environmental assessments of prospective areas of mineral occurrence must be different from that for already proven locations of mineral resources. The article presents quantitative characteristics of prospective areas of mineral occurrence presented on the aforementioned MGśP II map for Poland. We propose herein criteria for environmental evaluation of such prospective areas, differentiating them mainly depending on the type of mineral, manner of exploitation, surface area and land use legal forms, as well as possibility of future reclamation.

Sustainability of mining companies is of of high concern. The problem is specifically acute at companies that are monotownor monosettlement-forming. Sustainability of a mine depends in many ways on product quality and production resource-intensity. This article discusses formation of mineral quality indexes in terms of an open pit chrysotile mine. The studies took into account specific features of operation procedures implemented by each structural division of the mine. The analysis has found managerial and technological inconsistencies which affect quality and marketable product output, as well as efficiency of the mine in whole. The background for efficiency enhancement at a company is, by the authors’ opinion, consolidation of personnel subject to the single development strategy, namely: improvement of production and control efficiency, as well as use of available reserves and resources by means of better setup for production. The proposed approaches to planning mining operations and forming mineral quality allow higher quality of processing stock. In addition, a new model proposed for interaction between structural divisions of a mining company ensures improvement of general production indexes.

Undoubtedly is a technological revolution that has certainly focused on the interest of software development companies, companies of IT, hardware design, networks and artificial intelligence. A technological revolution that started a few years ago and has evolved rapidly, thanks to the technological evolution of IT and networks. It is a combination of many communication protocols, sensors and other intelligent technologies, the correlation between smart technologies, networks and services that all together complete processes in order to achieve the result for which they were installed. In advanced technology countries, both simple users and industry use IoT where sensors are simplified and automated at home and in industry, there is continuous monitoring, control and prediction of product failure for the benefit of efficient production of high quality products and control production at each stage of product processing / production. Someone could well think and say that all this is fantastic and that we have solved the problem of organization, easy life without further thoughts and worries since everything is done automatically.An IoT in an intelligent house could literally regulate everything, using sensors and appropriate software could talk with a human person, as well as someone could appropriately entice all that security and literally take full control of the premises of a home with consequences from minimal to catastrophic including the complete destruction of a home.

BACKGROUND As of the end of February 2020, 2019-nCoV is currently well controlled in China. However, the virus is now spreading globally. OBJECTIVE This study aimed to evaluate the effectiveness of outbreak prevention and control measures in a region. METHODS A model is built for find the best fit for two sets of data (the number of daily new diagnosed, and the risk value of incoming immigration population). The parameters (offset and time window) in the model can be used as the evaluation of effectiveness of outbreak prevention and control. RESULTS Through study, it is found that the parameter offset and time window in the model can accurately reflect the prevention effectiveness. Some related data and public news confirm this result. And this method has advantages over the method using R0 in two aspects. CONCLUSIONS If the epidemic situation is well controlled, the virus is not terrible. Now the daily new diagnosed patients in most regions of China is quickly reduced to zero or close to zero. Chinese can do a good job in the face of huge epidemic pressure. Therefore, if other countries can do well in prevention and control, the epidemic in those places can also pass quickly.

The Relationship

In 1994, an article appeared in the Italian journal Archeologia Medievale, written by Chris Wickham and Riccardo Francovich, entitled ‘Uno scavo archeologico ed il problema dello sviluppo della signoria territoriale: Rocca San Silvestro e i rapporti di produzione minerari’. It marked a breakthrough in the study of the exploitation of mineral resources (especially silver) in relation to forms of power, and the associated economic structure, and control of production between the twelfth and thirteenth centuries. On the basis of the data available to archeological research at the time, the article ended with a series of open questions, especially relating to the early medieval period. The new campaign of field research, focused on the mining landscape of the Colline Metallifere in southern Tuscany, has made it possible to gather more information. While the data that has now been gathered are not yet sufficient to give definite and complete answers to those questions, they nevertheless allow us to now formulate some hypotheses which may serve as the foundations for broader considerations as regards the relationship between the exploitation of a fundamental resource for the economy of the time, and the main players and agents in that system of exploitation, within a landscape that was undergoing transformation in the period between the early medieval period and the middle centuries of the Middle Ages.

Based on the constant need for safety and operational cost optimization, the air-cargo industry is continually evolving in the context of Industry 4.0. Used wisely, data can help the industry to provide critical resilience that will allow authorities to take proper measures/actions in response to unexpected disasters and secure societal protection. The “INTELLICONT” project combines state-of-the-art technologies blended with novel solutions to improve the loading/unloading time, the structural status awareness, and the safety and security of the air-cargo related operations (prior to, during, and after the flight), as well as to enhance their capabilities related to the execution of their duties. The suggested system is contextually aligned and harmonized with the existing international and EU regulations. In the present work, the remote monitoring and control system for intelligent aircraft cargo containers have been presented from the software perspective. The intelligent containers integrate three types of sensors, Structural Health Monitoring, fire suppression, and locking status indication. The focus has been given to the design and development of a Human Machine Interface (HMI) capable to visualize all related data for better and safer control of the aircraft cargo. It is shown that the system can contribute to making the air transportations safer, environmentally friendlier, faster and with the lowest possible cost.
